These [docs](https://docs.umbraco.com/umbraco-cms/reference/notifications/editormodel-notifications) demonstrate a solution to what I want to achieve. Only problem is, that

SendingContentNotification

seems to be deprecated in Umbraco 15. Or am I mistaken? Overall I want to > [...] manipulate the model used by the backoffice before it is loaded into an editor. to get "computed" properties. E.g. if a doc type has the integer property

A

, then a boolean computed value

A > 0

is loaded.

It's not available any more, but we're trying to see what people want to use it for so we can offer alternatives. Could you add what you would like to do in this discussion please? https://github.com/umbraco/Umbraco-CMS/discussions/16329 Thanks!

Will do. 🙂 However, the v15-docs still reference editor model notifications which is a little confusing.

Another good thing to feed back into that discussion thread then 😁
